Brishen Khaskem, prince of the Kai, has lived content as the nonessential spare heir to a throne secured many times over. A trade and political alliance between the human kingdom of Gaur and the Kai kingdom of Bast-Haradis requires that he marry a Gauri woman to seal the treaty. Always a dutiful son, Brishen agrees to the marriage and discovers his bride is as ugly as he expected and more beautiful than he could have imagined.

Ildiko, niece of the Gauri king, has always known her only worth to the royal family lay in a strategic marriage. Resigned to her fate, she is horrified to learn that her intended groom isn’t just a foreign aristocrat but the younger prince of a people neither familiar nor human. Bound to her new husband, Ildiko will leave behind all she’s known to embrace a man shrouded in darkness but with a soul forged by light.

Two people brought together by the trappings of duty and politics will discover they are destined for each other, even as the powers of a hostile kingdom scheme to tear them apart.
